EARL 1). PERRY, on ORCESTER,MAssAcHUsErtrs, AssIGNoR TO AMERIcAN cAR srRINKLER 00., or WORCESTER, MASSACHUSETTS, A coRPoRAT oN F MAssA- 8 Application filed April 16.

To all whomiz't may concern Be it known that-I, EARL D. FERRY, a

- citizen of the United. States, residing at Worcester, innthe county-of Worcester; and

State of Massachusetts, have invented a new andIuseful Street-Flusher, of whichthe fola trolley sprinkler andiespecially in conlowing is a specification.

. ,This invention relates totank car flushing .device and while .the principles thereof are :capable of usein connection'with other vehicles'it-is particularly adapted for use on nection" with that type designed for use on city S reets.

, The principal objects of the invention are to provlde -means in: connection with a sprinkler by which water canbe flushed on the street. surface under pressure for clean- I .ing purposes; to. prov de jconvenlentand practicable, means whereby the flushing operation" can. be. controlled by the; operator standingonthe car platform; to. provide simple means by which the main flushing nozzles can be carried by and manipulated with the usual sprinkler arm many other similarly arranged support, it being understood ,however that the sprinkling and flushing are operations which take place at different times; and l to provide an improved arrangement of flushing nozzles capableof cleaning the streets thoroughly and effectively.

supported below the tank for the purpose of delivering water from the tank under pressure to a flusher main 17. To this main is connectedby a pivot joint 18, a pipe 19 which is adapted to swing about the pivot and receive water from the main. This is provided also with a similar joint 20 for delivering water to a flusher nozzle 21. This nozzle is pivoted on a bracket 22'on the pipe 13 by means of a pivot pin 23, The relationashipofthe pivots 18, 20, 23 and 14 is such as to give substantially a parallel motion to the pipe 19 and the nozzle. Accordingly when the spray pipe 13 is folded up to the side of the car as shown at the left of Fig. 2, the flushing nozzle will be .moved into a position substantially parallel with it and with the side of the car so that it will not project out and will take up practically no room. But when the arm 13 swings outwardly it brings the flushing nozzle. to a position more and more nearly normal to the side of the car, the further the pipe swings. Consequently by swinging the spray pipe the necessary distancethe operator-has full control of the position and direction of the flushing nozzle. It willbe understood that, the flushing nozzle preferably has a long narrow slot for discharging a fanshaped sheet of water and that it is located at an angle to the ground so as to discharge in an efficient manner against the surface of the. ground and to flush all dirt and foreign matter along with it to the gutter. It will be observed also that the operator can swing the arm 13 back and forth if necessary to avoid teams andobstructions.

The discharge of the water from thepipe 17 to the pipe 19 is controlled by avalve 25, the stem ofwhichfis normally held in closing position by a spring 26. A flexible connection27 extends in, the opposite direction from the valve stem and is provided with a ball 28 at the end of the car which can be held in either one of two cleats 29 to hold the valve open or allow it to move back to closed position. 1 f

Alsoco'nnected withthe pipes 17 are a plurality of other pipes 30 each having a nozzle, as 21 21 and 21 similar to the nozzle 21 and eachcontrolled by a valve like the valve 25 having thehsame kind of connections. The flushing nozzles 21? are located at the ends of the car in such position that as the car moves, the one of these at the front directs its sheet of water between the tracks. The nozzles 21* are located at the opposite-corners of the car and are designed to direct a stream from the front to the side 5 toward that on which the nozzle 21; is operating as the car advances. The nozzles 21 are additional ones designed toforce a stream from the rear between the double tracks. It will be understood that ordinarily only the nozzles are used which are at the front, except 21, and each one is controlled separately by the connections 27.

It will be seen therefore that by this means an ordinary car sprinkler can be converted into a combination sprinkler and fiLISllGl'f very easily either afterit is builtor while being constructed and that the nozzles are V so arranged and controlled that the entire space, from the right hand side of a lei't hand track to the right hand curb, can be flushed effectively and efiicientlyby a single passage of the vehicle along the street and that provision is made for directing the flushing streams to any desired points, interruptingthem whenever necessary and controlling them in all .necessary ways.

1 Although I have illustratediand described only a single embodiment of the invention pipe, ofaflushing nozzle, boththe pipe and 40 nozzle being arranged to. deliver atone side of athe tank and to wet substantially the same street area, means for ,taking liquid from the tank and supplying it.to the fluslr ing nozzle underpressure, and means for snpplyingliquid from the ,tank through a different course tothe spray pipe independiently of said pressuremeans and at' a dif-"f v ferenttime.
